To all whom it may concern: Y

Be it known that I, Josnrn Bonn, a citizen of the United States,residing at Plano, in the county of Kendall and State of Illinois,theveinvented new and useful Improvements in Fertilizer-Distributers, ofwhich the following is a specification, reference being had .to thedrawings forming a part thereof.

The purpose of this invention is to provide an im roved mechanism .foroperating or contro lin the operation of the feeding device of aertilizer distributor.

.It consists of the features of construction shown and described as-indicated in the claims. i

In the drawings :Figure 1 is a side elevation of a fertilizer.distributer embodying this invention, broken away at the middle.part'to' condense in respect to length. Fig. '2 is a detail plan of therear portion of the structure shown in Fig. 1, having the conveyor apronin part broken away to disclose the mechanism below. Fig. 3 is a sectionat the line 3-3 on Fig. 1 upon an enlarged scale. Fig. 1 upon a scalecorresponding to Fig. 3. Fig. 5 is a. partly sectional detail sideelevation of the arts shown in Fig. 4, section being made at tl ie line5-5 on Fig. 4. Fig. 6 is a detail section at the line 6-6 on Fig. 5.Fig. 7 is a detail section at the line 7-7 on Fig. 2. Fig. 8 is a detailfront elevation of the hand lever and connections for'operating thefeedcontrolling devices. Fig. 9 is a detail section at the line 99 on Fi2.

This invention is a iertilizer distributor of the type whichcon'i-priscs a receptacle or Wagon box, A, whose bottom is formed by aconveyor apron, l3, propelled i'o'r dclivcring the material rearwardwithin reach of a distributor The convcvcr a iron, B, is )l'U- polled bychains, 1, 1, (only ono of which shown) drivcu by sprocket whorls, 2. 2,mounted on a conveyor-opcrnting shalt, 3, journnlcd upon the lowcr sill.A, ol the wagon box or rccc )tnclo. A. The shall, 3, is rotatcd forplopoiling the conveyor apron, l3, rearward, that is. in tho dircctionl'or dclivcring the l )2l(l,-"l moans ol' a clutch whccl or disk, 4,pinned lust to thc shaft, 2%, I and engaged by two clutch dcriccsmounted l rcspoctivcly in two l'orkod lovers, 5 and ti, both stridingtho whccl, '4, and pivoted on the shaft, 3, having the mounted in thefork for engaging the periphery of the Wheel, 3. These clutching deviceson the two clutch levers are oi identical construction and thedescription of one will sufiice for both.

Fig. 5 shows the clutch devices on the lever, 5, in connection withwhich they will now be described. Mounted for sliding between the forkarms of said lever, 5, in direction obliquely transverse to the lever,and for that purposebeing fitted into an obliquely transverse gnidewayformed in the crotch ol' the lever, as most'clearly seen in Fig. 4,there is a plunger bar, 7, which, besides being guided in the obli uetransverse direction of its guideway, llltll can be observed in Fig. 5,in which its oblique direction is defined by the shoulder,

5", is further guided lor reciprocation in the same direction by a stud,8, set into the lever and extending therefrom parallel to said obliqueguidewoy and the shoulder, 5*, thereof, the )lunger l'raving an oll'sctarm, 7, engaged with said guide stud, S, a spring coil about the studabove said arm, 7", being stopped by a nut, S, for operating upon theplunger to thrust it downward; that is to say, toward the narrower endof the space dclincd between the obli ue shoulder, 5", and the peripheryof the w 001, 4. See Fig. 5. The lungcr, 7, has an aperture, 7 lbdged aclutch roller, 9, whose diameter is a little greater than the thicknessof the plungdr, so that theroller, lodging against the rear obliqueshoulder, guidcway, protrrnlcs through the opposite face of the plnng. rfor engagement with the periphery of the wheel, 4, its protrusion beingsullicicnt. for such engagement whcn the plunger is at the limit of itsthrust in the dircction ol the narrow cnd ol thc interval mentioned,asindicatcd in dotted line in Fig. 5. When the plungcrisin thisposition, it will be soon that the rocking ol' the lever arm in which itis mounted about the shaft, 3, will cause the wheel to be engaged androtated in the direction of the arrow, ;r, on Fig. 5, the

clutching devicesin which is 5*, of the plunger clutch roller, -S),riding loosely over the peeach other about the shaft, 3, and the clutchdevices in both of them being mounted for engagement with the wheel inthe same direction, the alternate approach and retreat of the two leverswith respect to each other oscillating about the shaft will cause thewheel, 3, and thereby the shaft, to be rotated continuously with step bystep movement without appreciable mterval etween the ste s,provided'there is no appreciable inter va between the two movements inopposite directions of the two levers, because when one lever is rockingin direction to engage the wheel, the other lever rocking in oppositedirection is carrying its clutch roller ldly back over the wheel, and assoon as the motion of the levers is reversed, the second lever enagesthe wheel for rotation while the first fever returns idly to initialposition. The two levers are connected for causing them to thus rockalternately back and forward toward and from each other, by means of thebell-crank lever, 1011, fulcrumed at its angle on a stud axle, 12,mounted upon the side of the wagon box, A, the arm, 10, of thebell-crank lever being connected by a link, 13, t0 the lever, 5, whilethe other arm, 11, is connected by a link, 14, to the lever, .6, the twoforked leve rs, 5 and 6, being positioned on the shaft, 3, at an angleto each other approximating ninetydegrees at the intermediate point intheir respective paths of oscillation.

For communicating movements to the levers, 5 and 6, connected as abovedescribed, there is provided on the axle, D, of thetraction wheels, E,E, at one end of said axle, a face cam, 15, having a continuousserpentine cam slot, 15, on its inner face, and a lever, 16, having astud-and-roll abutment, 17, engaging the serpentine slot is. slidinglpivoted at 16 on a block, 18, mounted f dr ad- 'justment on longitudinalguideways, 19,

carried by the wagon box/A. The end of said lever, 16, remote from itson agement by means of the abutment, 17, wit the serpentine cam slot ispivotally connected to the lever, 5. This connection causes th srotation of the serpentine cam by rocking the lever, 16, at itsengagement with the cam slot back and forth toward the axis of theshaft, D, to rock the lever, 5, back and forth about the shaft, 3, thesliding of the lever, 16, at its sliding pivotal bearing, 16, serving toaccommodate the movement of its pivotal connection with the lever,5;about the slide block, 18, on which the lever, 16, is fulcrumedas'sta'ted, is connected by a rod, 20, with a hand lever, 21, fulcrumedat its lower end on the lower sill, A, of the wagon box, the upper endbeing in position for operation by the driver and having any convenientmeans, as the slide dog, 21*, for engaging the notched segment, 22, tolock it in any position to which it may be adjusted about its fulcrumfor adjusting the block, 18, on its guideways.

In order to disengage the shaft, 3, from its actuating clutchesdescribed, there is mounted loose on the shaft, 3, inside the outer forkarm of the lever, 5, which is mounted inside the forked lever, 6, a camdisk, 25, having two cam slots, 25*, 25, and there are pivoted on thesame pivots which connect the levers, 5 and 6, to the links, 13 and 14,respectively, the clutch releasers, 26, 26, each having a stud, 27,taking into one of the cam slots, 25, and also a stop stud, 28,projecting past the end of the corresponding clutch The disk, 25, has anoperating plunger, 7. arm, 29, which, for certain additional purposes,is formcd in a loop, 29, of which the other side bar, 29", is hung onthe shaft, 3, inside the wheel, 4; that is, between said wheel and theinner fork arm of the lever, 5. A rod, 30, connected to the arm, 29,extends forward and is connected at its forward end with a crank arm,31, of a rock shaft, 32, mounted in the lower sill, A, of the wagon box,and having a lever arm, 33, connected by a rod, 34, extending forwardlytherefrom to the lower end of the o ierating lever, 35, fulcrumed at thecenter of a segment, 36, at the forward end of the wagon box and inposition to be grasped by the driver at its upper end for rocking itback andforth and engaging it with and disengaging it from the segmentin a manner which needs no description. The rocking of the lever, 35,rearward at its upper end, causing it to pull the rod, 34, forward,rocks the shaft, 32, causing its crank arm, 31, by means of theconnecting rod, 30, to rock the plate, 25,

about the shaft, 3, in direction for causing it, by means of its camslots, 25,,to actuate the clutch releasers, for thrusting the clutchplun era, 7, outward with res ect to the whee 4, disengaging the elutcrollers, 9, from said wheel and interruptin the feeding action.- Thisaction is against tile tension of the springs on the guide studs, 8, 8.

In order to prom tly arrest the movement as well as to ho d the conveyoragainst traveling in either direction by reason of the inclination ofthe vehicle when operating on a hillside, a brake-shoe, 40, is providedpivoted on the sill, A, and operated by means of the loo 29, of thearm'29, through which the rake-shoe extends above a roller, 41, which ismounted in a bearin fork, 42, within the loo 29, and is provi ed, with aspring, 43, coiled around the stem, 42, of said bearing fork reactingagainst the lower end of the loop for foicing the roller up latter iseft hanging l'reelv between the against the shoe and thereby holding theforward,-that is,

shoe up against the wheel, 4. In order that the rotation of the camdisk, 25,- in direction for disengaging the clutch devices andterminating the driving action of said devices on the wheel,-4,'maypress the brake against the wheel, and the contrary movement of saiddevices for bringing them into action may release the wheelfroin thebrake-shoe, said brake-shoe, whichin general'is curved to fit theperiphery to the wheel is tapered for reducim it in thickness from apoint immediately below the wheel both hack toward the fulcrum and toits free end so that when the arm, 29, is operated for engaging theshaft, 3, with either driving train, the roller, 41, is thereby swungaround toward a reduced ortion of the brake shoe, and the I 'ri )hery ofthe wheel and the roller,- and when the hand lever, 35, is operated ineither direction for disengaging the shaft, 3,

.the resulting movement of the arm, 2!),

causes the brake shoe to be wedged between the .roller and the peripheryof the wheel.

For driving the conve'yer apron, B, in the opposite direction from whichit is driven by the clutch enga ed wheel, 4, there is provided on the axe, D, a sprocket wheel, 45, around which passes a chain, 46, for drivinga sprocket wheel, 47, which is loose on the shaft, 3. And rigid with thesprocket wheel, 47, there is one element of a clutch device whichconsists of an annular flange, 48, projecting from the Web of thesprocket wheel. Fast on the shaft adjacent to the flange and on theopposite side thereof from the body of the sprocket wheel, there is adisk, 40, to which there is )ivoted-a clutch dog, 50, overhung by theflange, 48, a spring, 51, being provided reacting against a stop, 52,which nojects froln the huh, 53, of the disk for holding the head of thedog normally inward against said hub whereby it is clear of abutments,48, 48, which project inwardly from the flange, 48, at opposite pointsin the circumference thereof. The disk, 49, has a slot, 49. Mountedloose on the shaft, 3, at the opposite side of the diskfrom that atwhich the sprocket wheel stands, there is a grooved Wheel, 54, having awedge-shaped finger, 54, projecting from it through the slot, 49, forengaging inside the head, 50", of tliQ- dog-that is, between said headand the hub, 53, .of the disk on which the dog is pivoted. A shippinglever, 55, engages the peripheral slot, 54*, of the wheel 54, for slidmgthe latter on the shaft, 3. When. the Wheel is moved by the shippinglever so as to thrust its wedge-shaped "linger, 54, through the slot,49", for forcing the head, 50", of the' dog outward, said dog being thusheld in the path of the abutments, 48", is engaged by one of them, andthe shaft, 3, is thereby rotated in directioirfor propelling the apronin its return path after delivering its load. The lever, 55, is operandl a rod, 56, connected with a lever arm, 3 with which the operating rod,34, above mcntioned is also connected, so that the hand lever, lit),when rocked rearward over the segment in the first part of that movemeutby means of the lever arm, 31, of the shaft, 32, adjusts the am plate,25, for disengaging the clutch devices from the wheel,

4..and holding the brake, 40, up against said wheel to arrest itsrotation, and in the latter art of said movement by means of the rod,56, operating the shipping lever, 54, it causes the engagement of theclutch devices described for connecting the sprocket wheel, 47, with theshaft, 3, for rotating it in the opposite direction from that in whichit was rotated by the clutch-driven Wheel, 4.
